Fiber-Optic Probe For Laser Velocimetry

Size and weight of optics reduced considerably. Proposed fiber-optic probe in laser velocimeter smaller (and, therefore, lighter in weight and more maneuverable) than previous probe. Proposed configuration is product of calculations and experiments showing virtual waists serve same purpose. Laser-velocimeter lens brought close to transfer lenses to focus on virtual waists, thereby shortening probe head considerably.
